An Annotation System for 3D Fluid Flow Visualization
Maria M. Loughlin, John F. Hughes · NASA Technical Reports Server (NASA) · 2007
Annotation is a key activity of data analysis. However, current data analysis systems focus almost exclusively on visualization. We propose a system which integrates annotations into a visualization system. Annotations are embedded in 3D data space, using the Post-it 1 metaphor. This embedding allows contextualbased information storage and retrieval, and facilitates information sharing in collaborative environments. We provide a traditional database filter and a Magic Lens 2 filter to create specialized views of the data. The system is customized for fluid flow applications, with features which allow users to store parameters of visualization tools and sketch 3D volumes. 1 Introduction In a study to characterize the data analysis process, Springmeyer et al. [13] observed scientists analyzing scientific data. They found that recording results and histories of analysis sessions is a key activity of data analysis. Two types of annotating were observed: ffl recording, or preserving ...
